Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1672S-2+ is determined by strict equivalence across the following critical parameters:

• Interface Protocol: I2C, 2-Wire Serial communication
• Time and Date Format: Binary format output
• Package Configuration: 8-SOIC (0.154", 3.90mm Width) surface mount
• Supply Voltage Range: 1.8V ~ 2.2V nominal operation
• Battery Backup Voltage: 1.3V ~ 3.63V
• Timekeeping Current: 500µA maximum at 2.2V
• Operating Temperature Range: -40°C ~ 85°C
• Functional Type: Binary Counter RTC with trickle-charger capability
• Compliance Standards: RoHS3 compliant, REACH unaffected

Only components matching all specified parameters across electrical characteristics, package dimensions, and functional features qualify as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

The DS1672S-2+ maintains active production status with full regulatory compliance. Component selection should prioritize parts with identical electrical specifications, matching package dimensions, and equivalent compliance certifications. RoHS3 compliance and REACH unaffected status are maintained across all equivalent parts, ensuring regulatory alignment for industrial and commercial applications. Moisture sensitivity level MSL 1 (Unlimited) provides flexibility for standard storage and handling conditions without specialized environmental controls.

Frequently Asked Questions (FAQ)

Q: What determines if a part is a true substitute for the DS1672S-2+? A: A substitute must match all critical parameters: I2C interface protocol, binary time/date format, 8-SOIC package dimensions, 1.8V–2.2V supply voltage, 1.3V–3.63V battery voltage, 500µA timekeeping current, -40°C to 85°C operating range, and trickle-charger functionality.

Q: Can parts with different package types replace the DS1672S-2+? A: No. The 8-SOIC (0.154", 3.90mm Width) package is a critical mechanical specification. Different package types are not interchangeable without PCB redesign.

Q: Are there voltage tolerance variations among equivalent parts? A: All equivalent parts specified in this reference maintain identical supply voltage ranges: 1.8V–2.2V nominal and 1.3V–3.63V battery backup. No variations are permitted.

Q: Does RoHS3 compliance affect substitution eligibility? A: Yes. All substitute parts must maintain RoHS3 compliance and REACH unaffected status to ensure regulatory alignment with the original component specification.

Q: What is the significance of MSL 1 (Unlimited) rating? A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements, simplifying inventory management and component handling procedures.

Q: Can the DS1672S-2+ be replaced with a different time format (e.g., BCD instead of Binary)? A: No. The binary time and date format is a functional requirement. Parts with different output formats are not equivalent and require firmware modifications.
